Researchers have developed SGFormer, a novel structure-aware matching network designed to improve local feature matching in photogrammetry. This new network addresses the issue of "attention divergence" in standard Transformers, where similar features in irrelevant regions can receive undue weight, particularly in scenes with large viewpoint variations. SGFormer incorporates a Triple-Structure-Attention (TSA) module that uses shallow local features to guide the Transformer's focus towards salient structures within overlapping regions, thereby enhancing matching accuracy and reliability.
